What causes falling objects to reach top velocity?
Earth's gravity
Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
Explain the effect that gravity has on the velocity of falling objects?
The force of gravity causes the falling object's velocity to grow in magnitude by 9.8 meters per second every second, while its direction remains constant.
How is gravity related to terminal velocity?
Based on the 9th grade book of Physical Science... Gravity is a force that acts between two masses, and Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. So, gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration... which ties together terminal velocity.
What is terminal velocity and what causes it?
Terminal velocity is an object's maximum speed while falling through the air, and it happens when the force created by air resistance is equal to the force of gravity.

How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]

Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.

How does the unbalanced force of gravity affect the horizontal and vertical velocity of an object in projectile?
In the absence of air resistance, the force of gravity has no effect on the horizontal component of a projectile's velocity, and causes the vertical component of its velocity to increase by 9.8 meters (32.2 feet) per second downward for every second of its flight.
What force causes mass movement?
gravity is the main cause of mass movements.
What is the force that causes the earth to orbit the sun?
GRAVITY!A2. Centripetal force. The velocity of the satellite around the earth causes centripetal, force which balances with the gravity, holding it in a circular orbit around the earth.
How does gravity relates to newtons 3 las of motion?
Newton's three laws of motion describe how forces affect motion. They have nothing to do with gravity, except that gravity is one of many possible causes of force.
How does gravity affects the acceleration of a falling object?
The bigger the object the faster it causes it to fall until it reaches terminal velocity, then it falls at a constant speed.
